Electronic devices are adapted to generate cryptographic keys from one or more biometrics. According to one examples, an electronic device can obtain a non-encoded bit string associated with biometric information for an individual. The non-encoded bit string can be treated as if it were encoded and a decoding operation may be applied to the bit string, resulting in a modified bit string. One or more cryptographic keys can then be generated based at least in part on the modified bit string. Other aspects, embodiments, and features are also included.

Aspects of the present disclosure provide a gesture recognition method and an apparatus for capturing gesture. The apparatus categorizes the raw data of a gesture into gesture elements, and utilizes the contextual dependency between the gesture elements to perform gesture recognition with a high degree of accuracy and small data size. A gesture may be formed by a sequence of one or more gesture elements.

Gesture recognition using gesture elements

System, apparatus, and methods are provided for protecting against malicious infrastructure in a wireless communication network. A system determines a trust metric for an access point and decides to avoid communication with the access point based on the trust metric for the access point. The trust metric may, for example, be a numeric value such as a probability of trustworthiness or a categorization of trustworthiness. The system may determine the trust metric by receiving a list of access points and their corresponding trust metrics and matching a potential access point to its listed trust metric. The system may try to avoid using an untrustworthy access point's services unless it deems the services important enough to risk the communication.

Method and apparatus for transmitting bulk emergency data while preserving user privacy

Prior to transmission, a message is divided into multiple transmission units. A sub-message authentication code is obtained for each of the transmission units. A composed message authentication code is obtained for the whole message based on the sub-message authentication codes of the multiple transmission units. The multiple transmission units and the composed message authentication code are then transmitted. A receiver of the message receives a plurality of transmission units corresponding to the message. A local sub-message authentication code is calculated by the receiver for each transmission unit. A local composed message authentication code is calculated by the receiver based on the local sub-message authentication codes for the plurality of transmission units. The local composed message authentication code is compared to a received composed message authentication code to determine the integrity and/or authenticity of the received message.

Composed message authentication code

Disclosed is a method for protecting a single sign-on domain from credential leakage. In the method, an authentication server provides an authentication cookie to a browser client. The cookie has at least one user authentication credential for the domain, and is associated with an authentication subdomain of the domain. The server receives the cookie from the browser client. Upon authentication of the user authentication credential in the received cookie, the server responds to the access request by forwarding, to the browser client, a limited-use cookie for the domain. The server receives a request from the content server to validate a session identifier of the limited-use cookie received from the browser client. Upon validation of the session identifier of the limited-use cookie, the server provides a valid session message to the content server for enabling the content server to forward requested content to the browser client.

A puzzle-based protocol is provided that allows a token and verifier to agree on a secure symmetric key for authentication between the token and verifier. A token stores a secret key and one or more puzzle-generating algorithms. The verifier independently obtains a plurality of puzzles associated with the token, pseudorandomly selects at least one of the puzzles, and solves it to obtain a puzzle secret and a puzzle identifier. The verifier generates a verifier key based on the puzzle secret. The verifier sends the puzzle identifier and an encoded version of the verifier key to the token. The token regenerates the puzzle secret using its puzzle-generating algorithms and the puzzle identifier. The token sends an encoded response to the verifier indicating that it knows the verifier key. The token and verifier may use the verifier key as a symmetric key for subsequent authentications.
